I have a device that produce PCM .wav files. I need to stream those files on

I need to add an encoding/compression level before sending bytes on the net,
thus reducing the traffic.
Any Idea? I begin trying the WM Encoder but I cannot set as source the file
already opened in writing by other process.

The sofware is in C#, .NET 1.1 and runs on Windows 2000, Windows XP and
Windows 2003 Server.

Thanks for whatever DirectShow, DirectX, WME or other solution come to yours
minds.

If you're not using DirectShow the easiest method is to use the ACM. You
take a block of data, give it to the ACM and it gives you compressed data
in the output buffer.

Look at the ACMApp sample. It's old and ugly but you should get the idea.
